[Pacemaker] cman heartbeat / interconnect configuration

Dear all,

after a little break I am coming back to my problem to configure heartbeat / interconnect with cman.
Meanwhile I know that cman is the recommended stack on RHEL6.
I have a pacemaker cluster with cman that is working, but now a would like to configure special interfaces for the direct node communication (heartbeat / interconnect /keep alive).

Unfortunately I do not understand how configure the interfaces. Can you please give me an advice?
Currently the cluster uses
corosync-cfgtool -s
Printing ring status.
Local node ID 2
                id            =
                status   = ring 0 active with no faults

bond0     Link encap:Ethernet  HWaddr C8:1F:66:D1:8B:23
          inet addr:  Bcast:  Mask:

The interfaces to configure are
em4       Link encap:Ethernet  HWaddr C8:1F:66:D1:8B:24
          inet addr:  Bcast:  Mask:
p6p4      Link encap:Ethernet  HWaddr 00:0A:F7:2F:A7:6F
          inet addr:  Bcast:  Mask:

my current configuration
cat /etc/cluster/cluster.conf
<cluster config_version="12" name="mysql-int-prod">
    <clusternode name="sv2828" nodeid="1">
        <method name="pcmk-redirect">
          <device name="pcmk" port="sv2828"/>
    <clusternode name="sv2827" nodeid="2">
        <method name="pcmk-redirect">
          <device name="pcmk" port="sv2827"/>
    <fencedevice agent="fence_pcmk" name="pcmk"/>

Best regards
Andreas Dvorak
